Kind Code:
B2
Abstract:
To provide a door structure capable of preventing a rotating shaft from dropping.SOLUTION: A door mechanism comprises a door frame, a door body 3, and a rotating mechanism 5 that rotatably connects the door frame and the door body 3. A frame material 31 of the door body 3 has a frame inclined part 31b extending obliquely with respect to a thickness direction of the door body 3. The rotating mechanism 5 comprises a bracket 6 fixed to the frame inclined part 31b, a rotating shaft 7 inserted into the bracket 6, and a bearing disposed in an upper frame of the door frame. When the rotating shaft 7 is located at an upper end position, an upper end portion of the rotating shaft 7 is located inside the bearing, and the door body 3 is rotatably connected to the upper frame. When the rotating shaft 7 drops to a drop position, the upper end portion of the rotating shaft 7 comes off the bearing, and the connection of the door body 3 with respect to the upper frame is released. The contact of the rotating shaft 7 with a screw N3 screwed or inserted into the frame inclined part 31b prevents the rotating shaft 7 from dropping to the drop position.SELECTED DRAWING: Figure 5
